Insight

Insight

Network Security Services (NSS) is a set of libraries designed to support cross-platform development of security-enabled client and server applications. Netscape Portable Runtime (NSPR) provides platform independence for non-GUI operating system facilities. A use-after-poison flaw and a heap-based buffer overflow flaw were found in the way NSS parsed certain ASN.1 structures. An attacker could use these flaws to cause NSS to crash or execute arbitrary code with the permissions of the user running an application compiled against the NSS library. (CVE-2015-7181, CVE-2015-7182) A heap-based buffer overflow was found in NSPR. An attacker could use this flaw to cause NSPR to crash or execute arbitrary code with the permissions of the user running an application compiled against the NSPR library. (CVE-2015-7183) Note: Applications using NSPR's PL_ARENA_ALLOCATE, PR_ARENA_ALLOCATE, PL_ARENA_GROW, or PR_ARENA_GROW macros need to be rebuild against the fixed nspr packages to completely resolve the CVE-2015-7183 issue. This erratum includes nss and nss-utils packages rebuilt against the fixed nspr version. Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Tyson Smith, David Keeler and Ryan Sleevi as the original reporter. All nss, nss-util and nspr users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
